In the section on determinants, shouldn't the $\mu$s and $\nu$s be subscripted?, i.e. $$a_{\mu_1}\overline{a}_{\nu_1}+\cdots +a_{\mu_n}\overline{a}_{\nu_n}=0$$

- No; they are entries of a matrix, so for example $a_{\mu 1}$ denotes the element in the $\mu$-th row and 1st column. TBloom 12:36, 22 April 2012 (CEST)

- Thanks for the clarification Thomas. I see that the matrix element notation is somewhat inconsistent across EoM, one sees both $a_{i j}$ and $a_{i,j}$. --Jjg 17:26, 22 April 2012 (CEST)
